That's a problem with your UI, rather than the code: it will happen like that whatever you do to validate, particularly if you validate in the TextChanged event and use MessageBoxes.

A better approach might be the way some website registration pages do it: a label beside the textbox (with foreground colour Red) that you put error messages into instead of using message boxes.
That way, the user can see the problem without being interrupted all the time.

When you do the conversion, store the results in class level private variables, and just execute the code:
nicshotsize.Text = (totalSize - shortFillSize).ToString();


Or better: don't use two TextBoxes at all, but NumericUpDowns instead - which won't let him enter "bad data" so it doesn't need validation.
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...
